Patent GB-2156885-A (GB)
Title: Coastline protection
Inventor: PETTY BRIAN
IPC: E02B3/04
Filed: 1984-03-13
Abstract: A coastal defence barrier 2 is formed by a line of coastal defence units 4 arranged end to end. Each unit has a vertically extending male conformation 6 at one end and a vertically extending female conformation 8 at the other. Units interengage to form a continuous barrier. They are restrained against relative movement, by the interengaging conformations 6 and 8, by piles 16 driven through the units into the sea bed, and by sea-bed material pumped into the units, and built up artificially or naturally, at the sides of the barrier. Thus, the ends 6 and 8 cannot grind against each other to form gaps which would breach the barrier and decrease its effectiveness. <IMAGE>

Title: Vehicle assembly production line
Inventor: PIGOTT NORMAN BRIAN
IPC: B62D65/02
Filed: 1984-03-15
Abstract: On a production line, component parts of a vehicle to be connected together are first loosely assembled, then fed to a framing station. At the framing station there are pillars 18 at either side of a path 11 through the station. These pillars carry tools 24, 26. The tools are adapted to position and hold the various component parts of the assembly whilst welding or glueing takes places. Each of the pillars carries tools which will cooperate with more than one different assembly type, and each pillar can be rotated about its vertical axis to present either one set or a different set of these tools to the path through the apparatus, so that different assemblies can follow one another sequentially on the production line, and all such assemblies will be correctly positioned and held whilst the component parts are secured together. Also described (Figure 4) is a production line in which a vehicle underbody 72 is delivered to a framing station, and body side panels 76 which are loaded on to horizontal arms 18 are brought into a vertical position located correctly relative to the underbody and welded thereto. <IMAGE>

Title: Viscometers
Inventor: BERRINGTON DAVID
IPC: G01N11/04
Filed: 1985-07-16
Abstract: A slit viscometer includes a demountable slit-shaped constriction (2) in a conduit (3, 4) between two reservoirs (LV1, LV2). Fluid is reversably forced between the reservoirs, the differential pressure across the slit being measured by transducer 7 and the flow rate calculated from the time taken for the liquid in reservoirs LV1, LV2 to pass conductivity probes 12, 13. Reservoirs AV1, AV2 supplied with air from source pipe 11 via solenoid S1, S2, S3, S4, provide a pressure differential between reservoirs LV1, LV2 to drive fluid from one to the other through constriction 2. The constriction is formed from two blocks provided with cooperating channels to form the slit. One channel contains a replaceable packing piece to enable the height of the slit to the altered. The reservoirs LV1, LV2 and constriction 2 are immersed in a temperature controlled oil bath. The operation of the viscometer is controlled by microcomputer 14. The fluid sample may be subject to constant differential pressure in each pass or to altered differential pressure in each pass. The temperature dependence of viscosity may be scanned at a single differential pressure. <IMAGE>

Title: Ultrasonic microstructural monitoring
Inventor: SCRUBY DR CHRISTOPHER BRIAN
IPC: G01N29/24
Filed: 1986-02-25
Abstract: A method and apparatus use forward scatter for monitoring the microstructural features, such as grain size, of an object (10). A point-source broad-band ultrasonic wave transmitter (laser 12) generates a sharp pulse of ultrasound at a point (18), which propagates through the object (10), and ultrasonic waves in the object (10) are detected at a second point (28) by a point broad-band detector (laser interferometer 14). Small signals detected after the arrival of a straight-through compression wave and before the arrival of a straight-through shear wave correspond to forward-scattered waves and are indicative of microstructural features lying substantially on the straight line between the generation point (18) and the detection point (28). Much of the scattered energy is mode-converted. <IMAGE>
